The mRNA expression of the ILs in the three groups.

Data are presented as mean ± SEM (standard error of the mean). Significantly higher mRNA expression in the TB group in contrast to the control group was detected for IL-10, IL-16, IL-17, IL-18, and IL-27. The mRNA expression of IL-10, IL-16, IL-18, and IL-27 was higher in the TB group than in the ID herniation group. a: Significant difference versus the control group (P<0.05). b: Significant difference versus the ID herniation group (P<0.05). c: Significant difference versus the TB group (P<0.05).
